The development of European Mobility of young in VET meet a crucial obstacle which is the recognitionof Learning outcomes gained abroad. Presently, it is not possible to recognize Knowledge, skills andcompetencies achieved in a foreign Vet system within the national pathway. ECVET is a solution toovercome these difficulties. Unfortunately the technical specifications have not been experimented. Thetrucks maintenance sector is a relevant study area because of its high level of internalization and of itspecific needs. Specific needs have been identified in this sector which are necessary to increase theemployability of young people. It would be done by integrating the European dimension in pathwayswithin a common core. The lack of recognition of the learning outcomes gained in the mobility contextwould be studied and solutions tested by concrete mobility actions. The ECVET Connexion study showshow it is complicate to prepare the implementation of the ECVET device in the frame of the VET offer inEurope.Especially, in several countries, VET systems are not ready for the elaboration and the implementation ofmodularized and individualized training pathways.We developed the European Class Truck Maintenance project which goals are:1. Experimenting the elaboration and the implementation of modules defined in term of learningoutcomes in training pathways.2. Testing the concept of “Mutual Trust” inside a partnership.3. Promoting the European working mobility in VET4. Developing and extending the curriculum with a recognized European learning experiences of studentsin vocational trainingThe partnership is composed by two levels of actors involved in the training delivery and the certificationprocess. The first one concerned the Training centres; which have the pedagogical resources and willimplement the project. The second one is composed by institutions (within competent bodies), which areLocal government (Sweden, Spain and Poland) or branch organisation (Sweden end France). Themajority of the partners have been involved in the ECVET connexion Study. They are identified by theEuropean Commission and in their own countries as expert on ECVET. This organisation will facilitatethe implementation of the project but also its sustainability. The OFFT ( Federal Office for Labour andTechnologies ) will join the project to specific status of Switzerland in the European Union.General description:The project aim is to test ECVET technical specifications through the integration of a European commoncore in national training path for Trucks maintenance. The creation of the Mutual trust need theelaboration of a specific process with tools to ensure the quality of the training achieved abroad.According to each national training delivery framework, the project would propose different way ofintegration of the European common core within curricula, taking care of the identification of learningoutcomes and the definition of modules in term of KSC. Also, the project would analyse the impact ofthe national certification system on the ECVET device implementation (according to the subsidiarityprinciple).The Pilot project would impact the VET system by proposing tools and methodology for implementingECVET. Also, the VET systems in Europe would be deeply impacted from the identification of needs tothe validation. All actors involved in the training delivery would be also concerned: they would have thepossibility to use concrete and adapted tools and methods for learning and implementing the ECVETdevice.
